Atlanta & West Point / Georgia Railroad / West Point Route 4-6-0 "Ten-wheeler" Locomotives of the USA


Class Details by Steve Llanso of Sweat House Media

Class 23 (Locobase 16188)

Data from "New Freight Engine for the Atlanta & West Point", Daily Railway Age, Volume XXXV, No 25a (24 June 1903), pp. 1063-1064. A & WP-WRA 10 - 1945 locomotive diagrams supplied in May 2005 by Allen Stanley from his extensive Raildata collection. Works numbers were 5900-5901 in 1903, 6247 in 1904, and 40404-40405 in 1906.

This was a large, burly design for a freight engine that adopted a relatively rare combination of the Ten-wheeler layout and 61" drivers. The DRA report stated that it was similar to some Canadian Pacific locomotives and offered "no great departure in design" from the norm, but that its construction was "simple and strong", all of its parts "readily accessible, and capable of "sustaining continued hard service."

And five decades of service four of the five engines rendered to the A&WP. 230 retired in January 1953, 228-229 were withdrawn two months later, and 226 was scrapped in July 1954.

The railroad sold the 227 to the Birmingham & Southeastern in 1923. There it ran until it was wrecked and scrapped in April 1953.


Class A (Locobase 7313)

Data from A & WP-WRA 10 - 1945 locomotive diagrams supplied in May 2005 by Allen Stanley from his extensive Raildata collection.

Both the Atlanta & West Point and the Western Railway of Alabama bought freight Ten-wheelers, all of them coming from Rogers (11) and Richmond (3). Among the works numbers from Rogers were 5899-5900 in 1903 (road #127, 226), 6246-6247 in 1904 (road 128, 230), 40404-40405 (road 228-229), and 43021 (road 225). One of the Richmond engines had work number 43021 in 1907 (road 225).

During the life of the class, they were rebuilt with superheaters, at which point most were fitted with piston valves and Southern valve gear. (130, at least, received Baker gear.)

Retirements began in the late 1930s and ended in the early 1950s.


Class A (Locobase 7315)

Data from A & WP-WRA 10 - 1945 locomotive diagrams supplied in May 2005 by Allen Stanley from his extensive Raildata collection. Works numbers were 40402-40403 in 1906.

Atlanta & West Point and the Western Railway of Alabama each bought a single A-class passenger engine from Alco's Rogers subsidiary in 1906 (road numbers 150 A & WP and 250 for the WRA). In the 1920s, each was substantially rebuilt. The 23" diameter cylinders were bushed to 22", Baker valve gear, 12" piston valves, and a superheater were added, and the engines renumbered as shown.

In their rebuilt form, the two Ten-wheelers remained in service to the end of steam.


Class A (Locobase 7316)

Data from A & WP-WRA 10 - 1945 locomotive diagrams supplied in May 2005 by Allen Stanley from his extensive Raildata collection.

The WPR, which combined the Atlanta & West Point and the Western Railway of Alabama, began its purchases of freight Ten-wheelers with this duo from Rogers in 1900.

In the mid-1920s, they were rebuilt with superheaters, 11" piston valves and Baker valve gear. Rebuilt and revived, the A & WP's 275 ran until 1947, the WRA' s 175 lasted until 1952.


Class A (Locobase 7324)

Data from GA 5 - 1947 locomotive diagrams supplied in May 2005 by Allen Stanley from his extensive Raildata collection. Works numbers were 24843-24844 in December 1904; 27157-27158 in December 1905; 27432-27433 in February 1906; 29706-29707, 29854-29855 in December 1906; 29950, 30021 in January 1907; 31084-31085, 31128-31130, 31165, 31177 in June; 31196, 34177-34178, 34191-34192 in January 1910; 36591-36592, 36624-36627 in May 1911; 37441-37442 in January 1912; 38313-38314, 38347-38348 in September; 38589-38590 in October.

The Ga RR settled on this design of Ten-wheeler and purchased it exclusively for 7 years. Some were deliverd with 340 tubes and thus had a total heating surface area of 2,851 sq ft. Even as late as 1947, some remained essentially as bought: D-slide valves and no flues. Possibly the only difference might have been the adoption of Walschaert radial valve gear.

34 (works 30021) was wrecked in June 1914. Most of the others were scrapped in the mid-1930s. 211-212 (works 34178, 34191) were rebuilt in 1922 with 21" cylinders. They lasted the longest, being scrapped in July 1954 along with 205. Nine others worked into the 1950s.


Class A (Locobase 9984)

Data from "New Locomotive for Atlanta & West Point RR", Locomotive Engineering, Vol XIII, No 5 (May 1900), pg. 203 and from A & WP-WRA locomotive diagrams supplied in May 2005 by Allen Stanley from his extensive Raildata collection.

"They are quite heavy engines, " said the anonymous author, "and are giving excellent service, having been put into passenger service at once and running perfectly cool ever since." Unfortunately, neither the article nor the locomotive diagrams supply the boiler's dimensions.


Class A - superheated (Locobase 7325)

Data from GA 5 - 1947 locomotive diagrams supplied in May 2005 by Allen Stanley from his extensive Raildata collection.

As noted in Locobase 7324, this design was by far the most numerous group of Ten-wheelers on the Georgia (which was part of the West Point Route assembly of Georgia-Alabama railroads). In the 1920s, the railroad started superheating the design, which led to other changes. The cylinders grew by an inch in diameter, slide valves were replaced by 11" piston valves, and 152 tubes were replaced by 24 flues holding 96 superheater elements.

Locobase can't say how many survived to the mid-1950s, but can report that at least 14 survived until the 1947 diagram book was updated. Some of these were only modified in the early 1940s.
